Happy CommIting! - GitLab CI/CD with Python André Alexandre Gomes1 August 13, 2019 [email protected] 

Abstract Russ Cox said “Software engineering is what happens to programming when you add time and other programmers”. André Gomes in his presentation will show you how GitLab CI/CD can help you to advance from programmer to software engineer by integrating and delivering software, including, but not limited to Python packages. 

(Rhetorical) Question Greetings! What’s the difference between programming and software engineering? 

(Rhetorical) Question Russ Cox says: Software engineering is what happens to programming when you add time and other programmers. 

Programming, Time and People Things get updated. Requirements change over time. People change jobs/projects. 

Programming, Time and People Being agile and releasing often matters. Testing matters. Code readability matters. Software development is a social effort that needs to me managed over time. 

CI/CD Continuous Integration (CI) Continuous Delivery (CD) Continuous Deployment (CD) 

Less jargon, please! CI/CD can be thought of as Happy CommIting! Pushing changes to a remote repository triggers safety belts, such as: does it pass the tests? does it compile? is the code properly formatted? . . . 

Cool, but how to. . . ? Today we will be looking at GitLab CI/CD. "Safety belts" are stages. A set of stages is a pipeline. 

Demo Let’s start simple and fast forward boring steps. Here’s the source code of a Hello World program (Python). Here’s the yaml file. Here are the pipelines. 

Conclusions Managing time and the social side of software development is key! A CI/CD mindset sets you apart from being just a programmer. Start integrating and deploying those python packages!
